When the molds have been given a half-turn intothe positionshown in ig. 7, the arms rocked, but not sufficien tly to bring the ollowed arms out of register with the ports, as .above. In this po- 'sition, however, the ports connect with pipes acting in the oplposite'directionfiom before,

y suctioh is then applied to aces 4'.a:n 3'and air is blown through faces 5Q'and 2. he mechanism, therefore, automatically gives the required action.

As the mold 2 .3 in Fig. 1 rises from the pul in, the vet the mold 4 5 starts to descend,

an 'mold 2, 3 .th '11 passes between a compressingfidevice, such as rollers 30 31 which com ress .t'he,mold,-faces' together.
